matplotilb中fig,ax = plt.subplots()的使用
把for循环中的i变量改为两个变量row和col,表示行和列的数量,然后用嵌套的for循环输出直方图,并在外层循环前面添加subplot方法,修改后的代码如下:
```
f = plt.figure(figsize=(12, 7))
f.suptitle('Label Counts for a Sample of Clients')
row = 2
col = 3
for i in range(row * col):
client_dataset = dataset.shuffle(buffer_size=len(train_images))
client_dataset = dataset.batch(batch_size=10)
example = next(iter(client_dataset))
label = example['label'].numpy()
unique_values, value_counts = np.unique(label, return_counts=True)
plt.subplot(row, col, i+1)
plt.bar(unique_values, value_counts)
plt.title('Client {}'.format(i))
plt.show()
```
